A Florida congresswoman is asking the U.S. Department of Education[1] to investigate allegations that K12, Inc., the Virginia-based for-profit virtual school company, used non-certified teachers to teach classes.

The request is one of series of blows for K12, which is trying to open a statewide virtual charter school in North Carolina. The company’s request has been denied, but the company and a non-profit organization set up to house the school are appealing the matter to the N.C. Court of Appeals.
